Cancer cells reprogram their metabolism to support growth and to mitigate cellular stressors. The serine synthesis pathway has been identified as a metabolic pathway frequently altered in cancers and there has been considerable interest in developing pharmacological agents to target this pathway. Here, we report a series of indole amides that inhibit human 3-phosphoglycerate dehydrogenase (PHGDH), the enzyme that catalyzes the first committed step of the serine synthesis pathway. Using X-ray crystallography, we show that the indole amides bind the NAD+ pocket of PHGDH. Through structure-based optimization we were able to develop compounds with low nanomolar affinities for PHGDH in an enzymatic IC50 assay. In cellular assays, the most potent compounds inhibited de novo serine synthesis with low micromolar to sub-micromolar activities and these compounds successfully abrogated the proliferation of cancer cells in serine free media. The indole amide series reported here represent an important improvement over previously published PHGDH inhibitors as they are markedly more potent and their mechanism of action is better defined.

-
Paragraph 0074; 0075; 0076; 0077; 0078; 0089; 0091-0093, (2018/11/21)
The invention relates to a method for preparing an oxazolidinone intermediate. Specifically, a synthesis procedure for the intermediate comprises: directly performing a “one-pot” reaction on a compound I, compound J or compound L without performing isolation, wherein a salt of a compound K is selected from a hydrochloride, sulfate, malate, tartrate, p-toluenesulfonate, or lactate, and wherein the symbol * in a compound indicates an atom of an R-type chirality or an S-type chirality or a racemate thereof.

Kamal, Ahmed,Khanna, G.B. Ramesh,Krishnaji,Tekumalla, Venkatesh,Ramu
, p. 1485 - 1494 (2007/10/03)
The lipase mediated kinetic resolution of pharmaceutically important β-hydroxy nitriles is described in high enantiomeric excesses and good yields. Some of the chiral β-hydroxy nitriles have been employed in the synthesis of β-adrenergic blocking agents such as propranolol, alprenolol and moprolol. This protocol has also been extended for the enantiopure preparation of 5-(4-tosyloxymethyl)-1,3-oxazolidine-2-one and 3-hydroxy-4-tosyloxybutanenitrile, chiral intermediates of high synthetic value.
